Description. Male ( Figs 22–23 ). Antennae orangish, basally speckled creamy and brown. Palpi orangish brown. Eyes dark brown, naked. Head and thorax mesially creamy with brown speckles, tegulae reddish or orangish brown. Abdomen from creamy to brown with more or less pronounced dorsal transversal brown stripes. Forewing. Forewing length: 26–30 mm; wingspan: 44–60 mm. Triangular, apex acute, outer margin slightly waved. Background color brown with creamy speckles. Pattern consists of orangish to reddish brown spot, two white to creamy waved medial lines, orangish to reddish brown eye-like spot in medial field with dark R-Cu vein, dark brown drop-like spot growing from it between M 3 and CuA 1 towards external field and faded fragmented orangish external line. Hindwing. Trapezoid. Background color brown with creamy medial line, external field with darker anal spot. Cilia creamy, gets darker on anal angle. Genitalia ( Figs 30–31 , 34 ). Similar to S. pallida (see above). Female ( Fig. 24 ). Bigger, darker and less contrasty than male. Antenna brownish, flagellum covered with creamy scales. Palpi orange. Eyes dark brown, naked. Head and thorax mesially creamy, tegulae orangish brown. Abdomen creamy with reddish patches. Forewing. Forewing length: 44 mm; wingspan: 94 mm. Oval-shaped, apex blunt, outer margin slightly waved. Background color orangish brown. Pattern consists of weakly pronounced orangish basal spot, two pale waved medial lines, weakly pronounced medial orangish eye-like spot and faded orangish fragmented external line. Cilia creamy with brownish tips. Hindwing. Egg-shaped. Background color orangish brown with creamy medial line. Cilia creamy, gets darker on anal angle. Genitalia is not studied (female has broken abdomen, genitalia slide is not found).

Variability. Dark elements of the wing pattern on male wings may get slightly paler than of the ones that figured ( Figs 22–23 ).

Diagnosis. The species is endemic to Flores and Sumba, male is paler than both: S. pallida from Java and Bali and S. gerry sp. n. from Sumatra. No clear difference in male genitalia is found between S. pallida , S. jaquie sp. n., S. gerry sp. n., S. dorsalis , and S. castanea . The species has up to 2.45% of pairwise distance from S. pallida , and 6.37–6.86% from S. castanea ( Fig. 40 ).

Distribution ( Fig. 38 ). Flores and Sumba.

Ecology. Adults were collected in December–January, April–May, and July–August from the altitudes between 5 (Luku Melolo, Sumba) to 1372 m (Ranaka, Flores) within the following ecoregions: Lesser Sundas and Sumba deciduous forests ( Dinerstein et al., 2017).

Etymology. The species is named in honor of Jacqueline “Jacquie” Sonia Durrell, the first wife and admirable companion of Gerald Durrell on numerous expeditions, a book writer, and a manager of the Jersey Zoo.
